AUTOMOBILE,

Application filed' Ifiay 20,

To all whom it may concern." i l I Be it known that I, GUs'rAvE A. SoHAoH'r,

a cltlzen of the United States of America,

and a IGSldBIlt of Cinclnnati, 1n the'county.

of Hamilton and State of ()mo, have invented certain new and useful Improvements in,

Automobiles, of whichthe following is a' specification.

This invention relatesto improvements in. automobiles, especially to those of the runabout type, and one object thereof is to simulate to a great extent. an ordinary side-. spring buggy having itsfore-wheels of lesser diameter than that of its hind-wheels and with a dashat the fore end of its body. V

One of the principal objects of theginven-' 'tion is to provide special m'echa'nism for variable speeds at which it is desired the. vehicle is to be driven on curves, hills and straight ways; another object is to provide. peculiar clutch-mechanism for coupling the driving-engine with the transmitting-mech anis m andstill another object is to provide peculiar hand and'foot lever and rod mechanism for actuating the engine, clutch, transmitting and. brake devices. I v

The invention "cons'is'tsin' certain novel features of the construction, 1' combinationand arrangement of the several parts of' the; improved automobile whereby certain" im= portant advantages and the above-named; objects are attained and the vehicle is madesimpler, cheaper, and otherwise better adapted and more convenient for general use, all as will be hereinafter fully described. 1 The salient andnovel features of the invention will be carefully defined in the claims. y

In the drawings accompanying this speci-. fication and forming a part thereof, Figure 1 is a plan view, with the fore-wheels removed, the rear upper part of the body broken away and the sides in section, the foot-board partly broken away and the rear tractionwheels partly broken away, all to clearly bring to view the working mechanism, es-. pecially the engine, clutch, transmitting and controlling devices; Fig. 2, a longitudinal. vertical section, taken on line a, a, of Fig. 1, but on a somewhat larger scale, to show the clutch and variable-speed transmitting devices; Fig. 3, an elevation of the lever-carrying side of the clutch-wheel, the shaft and sleeve being in cross-section; Fig. 4, a frag.- mentary section (on. a larger scale) of the clutch-wheel and friction driving-disk, show- Specification of LettersPatentL v Patented April 27, 1909. 1967f serial No. 374,695. r

' "ing the returning-spring and adjusting device for use in connection with the said disk to allow for proper leveling and wear Fig.5, a sideelevation of the vehicle (taken the reverse of the position seen in Fig. 1) with the wheels and the brake devices removed from the side on which the elevation is taken, a section being taken on',line b, b, of Fig. 7 in this view to clearly display the side-spring and reach features, the dash, the buggybody, the two diameter supporting-wheels, the brake device,an-d'thesteering and other controlling devices; Fig. 6, a fragmentary sectional elevation, taken on the line a, c, of

Fig. .7, clearly displaying the body, the dash having the fluid-receptacle and ventilator devices and the brake-mechanism, (the supportingwheels, engine, clutch and transmitting mechanism being omitted in this View Fig. 7 a fragmentary rear elevation of the vehicle, to show the link device (for suspending the body,) the brake devices, the rear-wheels and the brake-controlling devices, but'omitting the engine, clutch and transmitting devices and Fig. 8, a fragmentary elevation of the inner face of one of the rear sprocket-wheels showing the internal brake-shoes and the rock-block used for spreading said brake-shoes outward into acting frictional-contact with said sprocketwheel forsuitably braking the vehicle.

In these views, 1 represents the vehicle .body having the ordinary buggy-body form with a seat 2 and a dash-3.

4, 4 represent the fore-wheels and 5, 5 the hindw heels, the latter being of greater diameter than that of the fore-wheels, like untofthose of an ordinary buggy which my vehicle is designed tosimulate just as much aspossible, both for convenience and dainty appearance, and in order that I may secure more especially suit the tastes and use of those accustomed .to the ordinary buggy and make the change to a horseless vehicle less pronounced and more readilytaken up by such user. v e

16 represents the fore-axle and 7 the rearaxleconnecting with the hubs of said sets of wheels 4 and 5 respectively, as customary in automobiles. r

' ;8, 8 represent longitudinal side-springs centrallyconnected to the sills 9, 9 on the botton of the body 1 (as best seen in Figs. 5, 6' and 7,) and having pivotally-connected vertical double links lO at their respective the desired form of runabout adapted to r opposite outer ends, such links being pivotally-supported at their upper ends on the outer ends of transverse bars or rods .11, the latter, in turn, being supported by vertical posts 12, 12 secured at a suitable space apart on the axles 6 and 7 and having on the rear-axle only pendent loops or eyes 13, 13 for accommodating a transverse rocher brake-rod 14..

15 represents a block carried by the brakerod 14 at each of its ends, and 16 is a vertical bar carried by the rear-axle near each of its opposite ends, each such rigid bar having pivotally-attached at its upper end a pair of semicircular brake-shoes 17, 17 whose lower upturned ends 17 17 are spaced apart to accommodate between them the said blocks 15. The brake-rod 14 passes freely through the lower ends of the bars 16,

the latter forming bearings therefor so that the blocks 15 may be worked or rocked by means of the pivotal arm and lever connections 1 1, 14 with the foot-treadle 14 on the foot-board, and to thereby throw apart or expand the brake-shoes 17, 17 into frictionalcontact with the inner faces of the drivingsprockets 18, 18 mounted on the inner hubenlargenients 19, 19 of the hind-wheels.

10, 10 represent extensible rods connecting the rear rod 11 with the bottom of the body 1, so that the rear links 10, 10 can be rocked at their lower ends on the outer rear ends of the springs 8 and thus provide for the proper tension on the sprocketchains 20, 20 to prevent their sagging or becoming too loose on their wheels.

20, 20 represent sprocket-chains connecting wheels 18, 18 with the smaller sprockets 21, 21 at the outer ends of the transverse sleeved driving-shaft 22 mounted in bearings 23 on the side-sills about mid-length of the vehicle.

24 represents a drum suitably mounted on the shaft 22 and provided with two triple sets of transmitting pinions 25 internally mounted in channeled rings or boxes 26, (as best seen in Figs. 1 and 2,) such pinions engaging a pair of adjacently.=i:ounted d rivinggears 27, 27 on the sleeved shaft 22. The sleeving of the shaft 22 is, as (11St011121 for the usual purpose of allowing for differential speeds of the wheels on curves or in turning around corners.

28 is a grooved sleeve rigidly mounted on the central portion of drum 24, a ring or yoke 29 being freely mounted in the groove of said sleeve and engaged by the for: 30 of a horizontal lever 31 whose outer end has a lateral tubular extension 32 through which passes a transverse supporting-rod 33, the latter, in turn being mounted at its ends on the side-sills of the vehicle-body. (See Fig. 1.) An arm 34 having a slotted pivotal end 35 engaging the outer end of said tubular extension 32 projects rigidly at right-angles by means of the forked-lever 31 from the inner end of a lever 36, the latter being pivoted at 37 to the vehicle-bod) and having a linl; pivotally-connimted at its outer end, such ll11l-I extending rearward for pivotal-conneetion with the lower end of a vertical speed-controlling hand-lever 30.

10 is a wheel feathered to the drum 24-, the feather being shown at 24-, whereby said wheel may be recipromtcd along the drum The rim of wheel 40 is spaced or grooved and carries in such groove a suitable friction surface or tire 11, (Figs. 1 and 2), for engagement with the face of a dish 42 zrounted at a right-angle to the wheel 10 on the shouldered screwthreaded ends of a circular series of horizontal sliding bolts or pins 4-3 of a clutch-heel 4:4 Clutch-wheel 44- has a hub 45 encircling a longitudinal, short driving-shaftu47 that forms part of the engine 18, the latter being of any suitable type and construction, and mounted in the vehicle to the rear of said clutch-wheel 44. Each radial arm or spohe of the clutch-wheel 44 carries a lever 40 pivoted at its outer end 50 and pivotally-coupled at its inner end to a sliding ring 51 encircling both a sleeve 52 on shaft 4-7 and one end of the hub 45 on the clutch-wheel 1+1. The bolts or pins 43 are hollow a part of their lengths and also internally-threaded to receive shanks of screws 46, the latter, in turn, having flanges 43 against which bear spiral springs 13 encircling said screws 46 and bearing at their opposite ends against the. wheel-spokes. The outer squared ends of the screws 46 pass through enlarged openings 43 (best shown in Fig. 4) whereby due. allowance is made for the pivotal novement of the levers 4-0 in contact with said springs 43". as hereinafter more particularly referred to in the operation of the device. The threaded shanlts of the screws 46 are adapted to be turned to and from the hollow portions or sockets of the bolts or pins 43 that -arry the disk 42, for the purpose of providing for suitable adjustment of the di h in relation to the wheel 4-0, and, also, allowing or wear occasioned by the frictional-contact of the disk and the wheel 40. f n annular extension or hub 16 is e mstructed on the inner face of the disk 12, such annular extension having an. inner wearing surface or lining-brass freely encircling the outer hub-extension of the clutch-wheel 4-4 (Fig. 2) and thereby pernfitting said dish to IIIOVG to and from the adjacent outer face of said clutch wheel. The outer end 47 of the engine-shaft 47 is tapered (see Fig. 2) and the. center bore of the clutch-wheel 4-4- tapers to correspond thereto, a suitable connecting-ltcy being provided between the wheel and shaft.

53 ia a tripartite thrust-ring freely niounted on the sleeve 52 and provided with balls in its central disk to form a ball-bearing for the outer disks thereof.

54" is a ring'having a pair of shouldered in-j clmes or cam faces .54? (one only being shown in Fig. 2) and encircling the' outer end ofsaid sleeve 52 adjacent the tlirust ring 55 is a ring mounted on. the engine shaft 47 and provided with 'a-Ipair of shouldered andinc ined notches '56 corres onding to and engaged .by the said shoul; ered cam-f faces 54 of the ring 54. An arm 57 projects downward from the ring 54 and has pivotal rod and lever connections 58,259, 60, and 61 with a presser foot-treadle 62 mounted on seat. A suitable longitudinal reach 65 exthe body thereof and is connected at its opposite ends to the fore and rear axles as customaryin ordinary buggies or carriages. A

In operating the device the hand lever gtl is drawn toward the operator, to beginwith, so as to slidethe wheel 40 along the drum 24 and bring" its driving-face .41 into engagement with theface of disk 42 nearest its central portion or part of least diameter, thus providing for slow speed which isgradually accelerated by simply moving the said handlever forward and thereby sliding the wheel 40 in a reverse directiontoward the other end of drum 24 and causing its driving-face 41 to engage the face of disk 42 nearer its rim or portion of greater diameter. hand-wheel 68 is turned as usual to start the engine, and then the foot-treadle 62 is de-. pressed, thereby causing the arm 57 tomove laterally and partially rotate. the ring 54, such rotation, in turn, causing the inclined cam-faces 54 to bear again'st and ride up. ward on the corresponding inclined faces of the notches 56 in the ring 55 on the engineshaft 47. A thrust-motion is now imparted to the roller-bearing ring or washer 53, which, 7 in turn, forces the ring 51 toward'the clutch-.-

wheel 44 against the pressure of springs 43?. The bolts 43 carried by the levers 49 then slide outward in their bearings in the arms of the clutch-wheel 44 and said levers exert the desired pressure on the disk 42 carried by said bolts 43. The pressure on the disk 42 is then, in turn, transmitted by the outer face thereof to the frietionally-contacting rim 41 of the transversely-slidable wheel 40, the latter causing drum 24 to revolve by its feathered connection therewith. Foot treadle 62 is held down by means of any suitable device that may be readily released by the operator when it is desired to lessen or increase his speed. The springs 43 on the clutch-wheel 44, in expanding, readily return the bolts 43 to normal position with the friction-disk 42 retreated from activecontact with the rim of wheel 40, when-it is desired to slow up or stop the vehicle. The

The

drum 24 in rotating, carries with it the two sets of pinions 25, 25 that engage the gears 27, 27,'keyed, on the two part sleeved-shaft 22,;thelatter being thus differentially o-.-

erated to convey or transmit motion to t e driving sprocket-wheels so that the latter can turn at variable speeds on curves or corners when turning or swerving to the right 7 or left, as customary in the running of vehicles, especially of this character. f'he tapered end 47'" of the engine-shaft prevents the clutch-wheel riding. or forcing backward on such shaft, and provides a firm backing for the'clutch-Wheel when the disk .42 is-forcedinto driving-contact with the driven-wheel 40 that transmits power to the vehicle traction-wheels. tends along the center of the vehicle beneath Theibrake device isreadily actuated, when desired, by simply depressing the foottreadle 14 thereby causing the rocking of the blocks 15, 15, on their common rod 14, into active contact with the u turned ends 17 317 of the internal ivota brake-shoes [17, 17 and spreading the atteroutward into frictional-contactwith the inner face of the several sprocket-wheel extension hubs or drums 19 on the rear driving-wheels 5, 5 of the vehicle. Any suitable spring-actuated returning device on the foot-treadle 14? may be usedfor releasing theoperating-blocks 15 of the brake-shoes.

The narrowness of the wheel treads or rims and the weight and style of vehicle herein shown and described, readily enable the use of narrow solid tires, not well adapted to the heavier type of automobile having sets of described, a motor, a clutch-wheel keyed to the motor driving-shaft, a friction disk on the clutch wheel, means on the clutch wheel andengine-shaft for moving said disk to and from the face of the clutch-wheel, a transverse shaft, a drum mounted on the transverse shaft and carrying transmitting gears engaging gears keyed on the transverse shaft,

a friction-wheel feathered to said drum and with its rim differentially or variably engage-y from the adjacent outer face of the clutch-.

wheel, a transverse shaft having suitable to be attained, means for sliding the said wheel along the drum and transmitting means between the transverse shaft and the rear traction and supporting wheels of the vehicle.
